Nutrient burn?

is this nute burn? the stems are purple. Any saving these plants?

looks like nute burn but could be a ph problem any of the other look like this one

Just about all of them I flushed with ph 6.0 water and refilled tank with 250 ppm nutes. they came back a little yesterday.

keep'em on life support bro and talk to them!!! if they perkd up then i think you'll be alright!!

what medium are u using?

Ha yeah I was talkin to em, Im using hydroton some are in soil too. the pic is one that was in hydro I switched to soil. I did move them from one building to another the nutes were around 1200ppm at the old building and they seemed to be doing good. but they were under flourescents after the move they are under 1000w with about 900ppm before the flush now about 300 ppm
